Abstract
L'invention concerne une nanoparticule de silicium. La nanoparticule a des propriétés uniques. C'est une source d'émissions stimulées. Elle peut être en suspension dans un liquide ou dans un solide. Elle peut être mise sous forme de cristaux, d'agglomérats, de colloïdes ou de films. Selon l'invention, la nanoparticule est d'une dimension de l'ordre d'un nanomètre et n'excède pas environ deux nanomètres. Le procédé de production de ladite particule est une attaque électrochimique à progression graduelle de silicium non épitaxé. Il peut également s'en suivre une séparation de nanoparticules de la surface du silicium. Une fois séparées, des nanoparticules peuvent être mises sous forme de colloïdes, de cristaux, de films ou sous d'autres formes souhaitées, selon différents procédés. Les particules peuvent également être dotées d'un revêtement ou dopées.
